If you buy a new car, you must know this safety support feature.

Nowadays, every car is equipped by the manufacturer with standard safety systems such as airbags to protect the driver and passengers, seat belts or ABS anti-lock braking technology... However, in increasingly crowded traffic conditions, along with the development of technology, safety standards for consumer cars have been raised. The speed of technology development makes cars increasingly intelligent, including features that not only effectively support drivers in driving, but also contribute to ensuring safety when traveling.

According to Forbes magazine, many consumers are willing to spend more money to own safety features for their cars. Among them, there are features that effectively support drivers in driving, contribute to ensuring safety when participating in traffic... that are of most interest to consumers buying cars. In addition, some surveys by the Insurance Institute for Highway Safety (IIHS) also show that since driver assistance safety features were equipped on cars, the number of accidents occurring annually in the US has been reduced:

Adaptive Cruise Control (ACC)

Active cruise control helps the car automatically slow down when there is an obstacle ahead.

Upgraded from the Cruise Control system, Adaptive Cruise Control - ACC is now equipped on many car models, mainly luxury cars. This system not only allows the driver to set the vehicle's moving speed as desired, thereby releasing the accelerator pedal like using Cruise Control, but also has the ability to automatically slow down when there is an obstacle ahead.

This system works through sensors and radars mounted inside the front grille of the car to scan the distance and identify obstacles. In case of detecting a vehicle in front of it having a problem stopping or braking suddenly, the system will automatically reduce speed to maintain a safe distance to avoid collision.

Automatic Emergency Braking (AEB)

Automatic emergency braking after detecting danger is a car feature that many people are interested in when choosing to buy a car. Not only limited to high-end cars, the AEB system is now equipped by manufacturers on popular car models.

The automatic braking system is based on sensors from warning technology, some cars also have surveillance cameras, with collision detection function. Depending on the "advanced" level of the car, this technology can operate at different speeds, usually fluctuating around 30 km/h. In case of an unexpected situation ahead but the driver does not react in time, the system will detect and automatically brake the car to avoid a collision. Data from IIHS shows that in recent years, the number of "car-to-car" type car accidents has decreased by about 50%, after many car models were equipped by manufacturers.

Lane Departure Warning/Lane Keep

Lane departure warning and lane keeping assist are different systems, but both have the function of helping the vehicle to move stably, not to deviate from the lane while moving. The lane departure warning system works through sensors, cameras mounted on the front of the vehicle... When detecting the vehicle drifting out of the lane, the system will warn the driver with an image displayed on the central clock, sound, or create a slight vibration of the steering wheel to remind the driver.

Meanwhile, if the driver is negligent and causes the car to move out of the lane without turning on the turn signal, the lane keeping assist feature will intervene by gently controlling the steering wheel. On roads without lane dividing lines or with blurred lines, the system will not detect the situation of the car drifting out of the lane.

Blind Spot Detection

Blind spot warning systems use vehicle-mounted sensors to detect other vehicles in the blind spot area of ​​the rearview mirror.

During the driving course, drivers are instructed on how to adjust the rearview mirrors to minimize blind spots and observe the rear. However, in reality, not all car models are designed to completely eliminate blind spots when observing through the rearview mirrors.

The blind spot warning system installed on the car will help support the driver. This system uses sensors mounted on the car to detect other vehicles in the blind spot area of ​​the rearview mirror. If another vehicle is detected trying to pass, the system will transmit a warning signal, through the orange signal light on the rearview mirror to light up to notify the driver.

Rear view camera

This is a feature that is being widely applied on many car models. The rear camera basically helps the driver have a good view behind the car when reversing, while minimizing collisions with objects behind the car that the driver cannot see. Rear cameras often use wide-angle lenses to allow the driver to observe up to 180 degrees behind the car.
